Axial SCX24 Deadbolt vs Redcat Ascent-18Which Should You Buy?

Redcat priced the Ascent-18 to undercut the Axial SCX24 Deadbolt by a few dollars. That modest savings actually gets you a 1/18-scale truck that is physically larger in every dimension: 10.63 inches long versus 8.27, 5.31 inches wide versus 4.33, and 1.54 lbs versus 0.73 lbs. The Ascent-18 has more ground clearance at 1.57 inches versus 1.18. On paper, the Ascent-18 looks like the obvious pick with more truck for less money. In practice, the story has more layers.

The Ascent-18's larger size gives it inherent advantages in stability and obstacle clearance that physics alone dictates. The heavier weight provides better traction on smooth surfaces, and the bigger tires roll over things the SCX24's smaller wheels get stuck on or deflected by. The Ascent-18 also tops out at 5 mph versus the SCX24's 4 mph, and its 800mAh 2S battery puts out substantially longer runtime than the SCX24's 350mAh 2S. That is more than double the capacity, which translates directly to more crawling time per session. In a stock-versus-stock crawl on identical terrain, the Ascent-18 handles more features more easily just because it is a bigger, heavier truck.

But the SCX24 has something the Ascent-18 cannot match regardless of future development: the aftermarket. The SCX24 upgrade ecosystem is enormous and unmatched in any segment of the hobby at any scale. Hundreds of upgrade parts from dozens of manufacturers cover every single component on the truck: brass weights for improved traction, aluminum suspension links for durability, upgraded servos for better steering, beadlock wheels, performance crawling tires, LED lighting kits, body options ranging from Jeeps to Broncos to pickup trucks to military vehicles. The SCX24 community is massive and active, with dedicated forums, YouTube channels producing weekly content, and local crawling events in most major cities. The Ascent-18's aftermarket is growing but currently cannot compete in breadth or depth. If you plan to keep your truck completely stock, this difference does not matter. If you plan to modify, personalize, and project-build, it matters enormously and is probably the deciding factor.

Neither truck is waterproof, which is a limitation shared across this price range. Both use brushed motors and 4WD systems appropriate for their scale. Build quality on the SCX24 is good for 1/24 scale, though the stock servo is universally criticized as the truck's weak point and most owners replace it within the first month. Redcat's Ascent-18 build quality is decent for the price, with a metal chassis plate and reasonable component quality throughout, though it lacks the refinement and precision of the Axial in areas like shock damping and steering feel.

Runtime strongly favors the Ascent-18 on stock hardware. That 800mAh battery versus 350mAh is more than double the capacity, translating to 30+ minutes of crawling versus 15-20 for the SCX24. You can buy larger aftermarket batteries for the SCX24 to close this gap, but that is an additional cost and modification that the Ascent-18 does not require.

Value is pretty complex here. The Ascent-18 at its budget-friendly price gives you more truck for less money in the immediate term. Better stock performance, longer runtime, and a larger, more capable platform right out of the box. The SCX24 at its budget-friendly price gives you access to the best mini crawler ecosystem in the hobby and a platform you can customize and evolve for years. For a kid or casual user who wants to crawl out of the box and enjoy it as-is, the Ascent-18 is the better buy. For a hobbyist who wants a long-term project with unlimited upgrade potential and a passionate community to share it with, the SCX24's ecosystem is worth the smaller starting platform and the few extra dollars.
